Abstract:Television broadcasters and Multichannel Video Program Distributors (MVPDs) are required to put in place procedures, software, and hardware to “effectively control program-to-interstitial loudness … and loudness management at the boundaries of programs and interstitial content.” Objective data must be supplied to the FCC to support compliance with the legislation as well as timely resolution of listener complaints. Similar rules have been developed in the UK and other parts of the world. Members of our panel of experts have worked tirelessly to either create loudness control recommendations that have become the law or to bring those recommendations to implementation at the companies they represent. This session will cover the FCC’s Report and Order on the CALM Act, the development of the ATS’s A/85 Recommended Practice that is now part of the U.S. legislation and both domestic and European technical developments by major media distributors and P/LOUD.
